IDAHO FALLS, ID — An Idaho family got more than they bargained for when a giant hole opened up in the floor of their garage.

Early Tuesday morning around 4 a.m., Brittany Bush and her husband woke up to loud noise. At first, they thought someone was trying to break into their house but, after not finding anything, they went back to bed. Later that same day, Brittany went to the garage and found what had made the noise.

“As I was pushing the garage door up, my right foot was stepping into the garage and just kept going down,” Brittany told EastIdahoNews.com. “I was holding onto the garage door and looked down and just started screaming. I’m like, ‘Our whole garage is sunk down!’”

While having a giant hole open up in your garage floor is surprising enough, the biggest shock came when the family realized that it wasn’t just a simple sinkhole. There was a room hidden under what used to be the garage floor.

They could see shelving units that held children’s toys, a woman’s handbag, hair curlers and a letter.
